Abstract
In an example, a method includes obtaining an indication of a deviation from an expected dimension of at least one dimension of an object generated using an additive manufacturing apparatus. A geometrical compensation model to apply to object model data for generating objects using additive manufacturing to compensate for anticipated deviations in dimensions may be determined from the obtained indication. The geometrical compensation model may comprise a first value to apply to object model data to modify a specification of an external dimension; and a second, different, value to apply to object model data to modify a specification of an internal dimension.
Claims15
A method comprising:
- obtaining an indication of a deviation from an expected dimension of at least one dimension of an object generated using an additive manufacturing apparatus;
- and
- determining, using at least one processor and based on the obtained indication, a geometrical compensation model to apply to object model data for generating objects using additive manufacturing to compensate for anticipated deviations in dimensions, the geometrical compensation model comprising:
- a first value to apply to object model data to modify a specification of an external dimension;
- and
- a second, different, value to apply to object model data to modify a specification of an internal dimension.
Apparatus comprising processing circuitry, the processing circuitry comprising:
- a geometrical compensation module to apply a compensation to object model data describing an object to be generated in additive manufacturing to correct for anticipated variations in dimensions, where the geometrical compensation module is apply the compensation using:
- a first value to object model data to correct for anticipated variations in an external dimension of the object;
- and
- a second, different, value to object model data to correct for anticipated variations in an internal dimension of the object.
A tangible machine-readable medium storing instructions which, when executed by at least one processor, cause the at least one processor to:
- separately identify internal and external dimensions of an object to be generated using additive manufacturing;
- and
- apply a first geometrical transformation to a virtual model of the object to modify the identified internal dimensions and a second, different geometrical transformation to modify the identified external dimensions.
